Guhitamo ubukonje bukwiye bwa Hydroxypropyl Methylcellulose (HPMC) kugirango itange ifu yifu yumye ningirakamaro kugirango habeho gukora neza nibiranga ibicuruzwa byanyuma. Ihitamo rigira ingaruka kumitungo myinshi, harimo kubika amazi, gukora, guhuza, nigihe cyo gufungura. Hano haribisobanuro byuzuye bigufasha gusobanukirwa no guhitamo neza neza HPMC kugirango ubone ifu yumye yumye.
Gusobanukirwa HPMC
Hydroxypropyl Methylcellulose (HPMC) ni ether itari ionic selulose ether ikozwe muri selile naturel ya selile isanzwe ikoresheje uburyo bwa chimique. Ikora nkibibyimbye, bihuza, firime-yahoze, hamwe nogukoresha amazi mumashanyarazi yumye.
Imikorere y'ingenzi ya HPMC muri Mortar yumye
Kubika Amazi: Yemeza neza amazi ya sima na lime, byongera imikorere kandi bigabanya gucika.
Umubyimba: Itezimbere ububobere, bigira uruhare mubikorwa byiza no gutuza kwa minisiteri.
Adhesion: Yongera imbaraga zo guhuza za minisiteri na substrate.
Imikorere: Ihindura ubworoherane bwo gusaba no koroshya kurangiza.
Gufungura Igihe: Yagura igihe minisiteri ikomeza gukora nyuma yo kuvanga namazi.
Ibintu ugomba gusuzuma muguhitamo HPMC Viscosity
Ibisabwa:
Urukuta rwa Putty: Bisaba kuringaniza hagati yo gukora no kubika amazi. Mubisanzwe, ubukonje buciriritse HPMC (50.000 kugeza 100.000 mPa.s) irakwiriye.
Amatafari ya Tile: Ubukonje bukabije (100.000 kugeza 200.000 mPa.s) burakenewe kugirango hafatwe neza kandi birwanya kunyerera.
Skim Coat: Hasi kugeza hagati (20.000 kugeza 60.000 mPa.s) kugirango ukoreshe neza kandi urangize.
Ibidukikije:
Ubushyuhe n'ubushuhe: Ubukonje bwinshi HPMC irashobora gutanga amazi meza mugihe gishyushye kandi cyumye, bigatuma gukora igihe kirekire no kugabanya gukama imburagihe.
Ibintu fatizo biranga:
Igipimo cya Porosity na Absorption Igipimo: Kubutaka bwinjiza cyane, ubukonje bwinshi HPMC ifasha mukugumana ubuhehere igihe kirekire, kwirinda gukama vuba no kwemeza neza.
Ibyifuzo Byifuzwa:
Igikorwa: Ubukonje buhanitse HPMC itanga ubudahwema, bushobora kunoza ubworoherane bwo gukwirakwiza no kugabanya kugabanuka.
Gufungura Igihe: Igihe kirekire cyo gufungura kirifuzwa kubikorwa binini binini cyangwa ikirere gishyushye, bigerwaho hamwe nubwiza bwinshi HPMC.
Kurwanya Sag: Ubukonje buhanitse butanga imbaraga nziza zo kurwanya, ingirakamaro kubikorwa bihagaritse.
Intambwe zifatika muguhitamo HPMC Viscosity
Suzuma Ubwoko bwo gusaba:
Menya niba ibicuruzwa bigenewe urukuta, ibiti bifata neza, cyangwa ikoti rya skim.
Sobanukirwa ibikenewe byihariye nko kubika amazi, gufatira hamwe, nigihe cyo gufungura.
Kwipimisha Laboratoire:
Kora ibizamini bito hamwe na HPMC itandukanye kugirango urebe imikorere.
Gupima ibipimo nko kubika amazi, gukora, n'imbaraga zifatika.
Guhindura Ukurikije Ibisubizo:
Hindura neza ihitamo rya viscosity ukurikije ibisubizo byikizamini.
Menya neza ko ibicuruzwa byanyuma byujuje ibisabwa byose nibisabwa.
Ibisanzwe Viscosity Urwego Kubikorwa Bitandukanye
Urukuta rwa Putty: 50.000 kugeza 100.000 mPa.s
Amatafari ya Tile: 100.000 kugeza 200.000 mPa.s
Ikoti rya Skim: 20.000 kugeza 60.000 mPa.s
Ingaruka za Viscosity kumikorere
Viscosity nkeya HPMC (<50.000 mPa.s): Itanga imikorere myiza kandi ikoreshwa neza. Bidafite akamaro mukubika amazi no kurwanya sag. Bikwiranye namakoti meza yo kurangiza hamwe namakoti ya skim. Hagati ya Viscosity HPMC (50.000 - 100.000 mPa.s): Iringaniza gufata amazi no gukora. Bikwiranye nurukuta rusanzwe rushyirwa mubikorwa. Kongera imbaraga hamwe no gufungura igihe giciriritse. Viscosity HPMC (> 100.000 mPa.s):
Kubika amazi meza hamwe nibintu bifatika.
Ibyiza bya sag kurwanya no gufungura igihe.
Byiza kuri tile yometse hamwe nibikorwa-byinshi byo gushira.
Guhitamo neza neza HPMC kubutaka bwa poro yumye yumusaruro wumuti nicyemezo cyibice byinshi bigira ingaruka kumikorere yibikorwa muri rusange. Urebye ibisabwa bisabwa, ibidukikije, ibidukikije bifatika, nibikorwa byifuzwa, ababikora barashobora guhitamo icyiciro cya HPMC. Gukora ibizamini bya laboratoire byuzuye kandi bigahinduka byemeza ko ubwiza bwatoranijwe bwujuje ibyifuzo byihariye bigenewe porogaramu, bikavamo ibicuruzwa byiza-byiza, byizewe.
